A wheel steering mechanism for baby stroller is capable of selecting the controls of the engaging and releasing of the positioning pin and the wheel seat by making use of the downward pressing of the pressing key in single direction. When the pressing key is pressed down for the first time to make the positioning pin engage with the wheel seat, the wheel seat appears to be in the status of fixed-direction steering. When the pressing key is pressed down for the second time to make the positioning pin separate from the wheel seat, the wheel assembly is capable of restoring back to the status of free steering. Based on this kind of design, the invention is capable of providing the operator to directly step on the pressing key in order to control the status of either fixed-direction steering or non-fixed-direction steering of the wheel assembly. In this way, the invention is capable of providing the operator with the advantages that the operation is easy to handle and all he or she has to do is exerting force to press the pressing key to move it downward making the invention has the effect of not damaging the operator's shoe vamp.
